CHARLES lVI. BUMP, OF BAY CITY, MICHIGAN.

MASSAGING-MACI-IIN E.

Application filed September 18, 1914.

To all whom it may concern:

Be it known that I, CHARLES M. BUMP, a citizen of the United States of America, residing at Bay City, in the county of Bay and State of Michigan, have invented certain new and useful Improvements in Massag ing-Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to massaging machines and is of the type adapted for the massaging of the back adjacent the spinal column in a manner similar to the osteopathic treatment of the spine.

It is the object and purpose of my invention to provide a machine of this kind by which one can give massaging treatments of this character to himself without the necessity of going to a skilled practitioner.

It is a further object of the invention to combine with the structure a means for giving electrical treatments in connection with the massaging treatments.

Other objects and purposes will be apparent as the description progresses, and as understanding is had of the construction shown in the accompanying drawings in which:

Figure 1 is a perspective view of my massaging machine. Fig. 2 is an end elevation of an element of the machine. Fig. 3 is a side view of said element with parts shown in section. Fig. 4: indicates in dotted out line the normal position of the parts of the machine and in full lines the extreme position occupied by said parts in the course of a treatment therewith. Fig. 5 is a detail of the support for said machine; and Fig. 6 illustrates, diagrammatically, the method or manner in which treatments with said machine are taken.

Like reference characters refer to like parts throughout the several views of the drawing.

In the construction of my massaging machine, a base 1, preferably of metal, is provided and at each end thereof are secured upright sheet metal sections 2 having bent therefrom the angular extensions 3 which bear against and are secured at the ends of the base 1. At the upper corners of each of the sections 2 are pivoted the metal segments 4 which extend toward each other and which at their adjacent ends are provided with Specification of Letters Patent.

Serial No. 862,283.

gear teeth 5 meshing one with the other as shown. Adjacent a lower corner of each segment 4 is pivotally attached the upwardly extending sheet metal members 6 which cross each other as shown and which are pivotally connected together, a rod 7 extending between and furnishing the pivotal connection for each pair of the members 6. Rods 8' are also provided extending between the lower ends of members 6 and passing through the segments 4:, the ends thereof being received in the slots 9 cut in sections 2.

At their upper ends each of the members 6 are provided with inturned horizontal portions 10 to which are attached the jaws 11, the outer edges of which are provided with corrugated formations 12 simulating the knuckles of a persons hand. There are two of these aws 11 as shown carried by and between a pairrof the spaced apart members 6. Rods 13 extend between the members 6 as shown, passing through openings therein, the pair of rods 13 being spaced apart and having interposed therebetween coil springs 14 under tension, the normal tendency of which is to draw the rods and consequently the jaws 11 closer together.

A link 15 is pivotally attached on the inner side of each of the members 6 as shown in Fig. l, and at their upper ends the links of a pair of members 6 are brought together and pivotally secured adjacent the upper end of a member 16 which is positioned substantially upright and which at its lower end is slotted at 17 passing over the rod 7 There are two of'these members 16 which are spaced apart and lie adjacent the spaced apart pairs of members 6 and at their upper ends they are secured to the downturned ends of a cross bar 18, which carries on the upper face thereof, a bar 19 consisting of a core formed preferably of wood and covered with a fabric covering 20, preferably of felt. The wood center or core is bored for a portion of its length for the reception of a wire 21 which may be carried to any convenient place for connection with a source of electric energy.

The machine as thus constructed is adapted to be supported with the base 1 in a vertical plane as indicated in Fig. 6, a bracket 22 being attached to any suitable support such as a wall. or the like and carrying a depending rod 23 which passes through openings in the sections 2 of the machine as shown in Fig. 1 and which carries the collar the beginning of said ofieration th me-meet 24: adjustable along the length of rod. 23 and adapted to be fixedv in place at any point along the length thereof by the set screw 25. The base 1 on the underside thereof is provided with a plurality of members 26 preferably of rubber, or at least rubber:

covered, which may bear against the wall as shown in Fig. 6 withoilt danger of marring or defacing it. e v a Iii tfe operation of the rnachin'e it'is' strp' ported with the base ina vertical plane indicated in Fig. 6 and-the colla r 24 ml: 'lls'ted to any desired position" on the rod23; The person takifig the treatment pbsitions' himself before the machine with the terru'gated sections at either side of the Spinal column, and their by" pressing: back: ward against the maehi'ne the tension of the s rings 14% may be oyercome' andthe jaws wh'ch' terminate in the rnrgated po tnae 12 may be forced apart, this peratidri befitg indicated in v show the initial position at the beginning of the operation and full lines the final fi'o sition. It wiltbe apparent that in the-petite f this operation the corrugated portions 12 corrs'oiiding to the knuckles of a person s will press against and massa epor tions of the back adjacent the spinal. olumn; Be inning immediately adj adept: the spixial olumn and working; outwardly therefrom,

a manner similar to the osteopathic treatmeat as giv nby eraetitidfierswhe use the knuckles of the closed hand" to give said treatmeiit; Itwiu" also be apparent that at 19 will matte in conta t-with the b'a' k but as the a operiedfa short distance wifl c e in Contact therewith and will be re co tact'diirifig'theilatterfiartof the 0p; treat-n as SllZWV I'i in Fig, 4, S tan-embe 19 bein carried" to the rear the o ening at the jaws.' Item be-noted} iri this conne'c tion that, if desired, an electrical treatment Ina-y'- be taken connection with the masaging treatment. The wire army be can: ,aeete with any suitatle soiirc'e or eie tfit entrant such as an electric battery and the ethetwi'rei of the-battery may be held in the hand" of the; person operated il'pori" whe eubdn as the- Back coi'rie's'ii'i contact with the rlherfiber' 19, the 'e'i'r'ciiit will'be completed, it designed in each c'a'seth'at the cover shall be moistened tjo fierinit' the ready cond'uctioii'of the electric current.

Thiswill be'practically necessary Whenever an electrical treatmen-tisaalso had. If however, the; electrical treatment is not desired, the massaging treatfileiit be taken even with the body partially clothed in which case the stronger tension exerted by the additional swin er-4r will not serve to" injure the taste treated the same as if the" corrugated parts 12 wee in direct Contact with the flesh; Al'so when; the body is artially cl oth'ed the me'riiber' 19 will serveito keep the" clothing against the body so that it will not be caught between" the jaws 1I- and atall tin-res in the operation of the machine, thepniernber 19' serves to limit the approach ofthejawstoward eachother, said j'aw s' not being permitted to were close 'tege'tlier which would be, it many cases, undesirable:
